73. | It is reported in this paper that by using the absorption spectrum of the interfering component as the denominator factor, the first derivative ratio spectra of the component mixture can be obtained, and the inter ference of one of the components can thus be eliminated. |
| 利用混合物的波谱除以干扰组分的波谱得比值波谱,对波长求导得比值导数波谱,由此可消除干扰组分的吸光度叠加效应。 |
